docker安装minion文件系统

docker安装minion文件系统

一、创建文件夹

mkdir -p  /mydata/minio/config

mkdir -p  /mydata/minio/data

二、安装运行挂载容器

docker run \

\>  -p 9000:9000\

\>  -p 9001:9001\

\>  --name minio\

\>  -v /mydata/minio/data:/data\

\>  -v /mydata/minio/config:/root/.minio\

\>  -e "MINIO_ROOT_USER=root"\

\>  -e "MINIO_ROOT_PASSWORD=root12345"\

\>  quay.io/minio/minio server /data --console-address":9001"

⚠️注意：此处的客户端密码必须是大于等于8位

三、跟随docker启动

docker update minio --restart=always

四、整合spring boot

1、导入依赖

<!--minio-->
<dependency>
    <groupId>io.minio</groupId>
    <artifactId>minio</artifactId>
    <version>8.3.0</version>
</dependency>

2、设置配置项

​ 1.创建配置类

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

/**
 * Description:
 *
 * @author : Zhao Yao
 * @date : 2022/08/08
 */
@Data
@Component
@ConfigurationProperties(prefix = "minio")
public class MinioProperties {
    /**
     * 账号
     */
    private  String accessKey;
    /**
     * 密码
     */
    private  String secretKey;
    /**
     * 地址
     */
    private String endpoint;
    /**
     * 🪣名
     */
    private String bucketName;
}

2.配置链接Minio对象并注入到spring容器中

import io.minio.MinioClient;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * Description:
 *
 * @author : Zhao Yao
 * @date : 2022/08/08
 */
@Configuration
public class MinioConfig {
    final MinioProperties minioProperties;

    public MinioConfig(MinioProperties minioProperties) {
        this.minioProperties = minioProperties;
    }
    @Bean("minioClient")
    public MinioClient minioClient() {
         return MinioClient.builder()
                .endpoint(minioProperties.getEndpoint())
                .credentials(minioProperties.getAccessKey(),minioProperties.getSecretKey()).build();
    }


}

3.创建Minio工具类方便操作🪣

import io.minio.*;
import io.minio.messages.DeleteError;
import io.minio.messages.DeleteObject;
import io.minio.messages.Item;

import org.apache.tomcat.util.http.fileupload.IOUtils;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.http.ResponseEntity;
import org.springframework.stereotype.Component;
import org.springframework.web.multipart.MultipartFile;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.UnsupportedEncodingException;
import java.net.URLEncoder;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
import java.util.stream.Collectors;


@Data
public class ObjectItem {
    private String objectName;
    private Long size;
}

/**

 */
@Component
public class MinioUtilS {
    private final MinioClient minioClient;

    @Value("${minio.bucketName}")
    private String bucketName;

    public MinioUtilS(MinioClient minioClient) {
        this.minioClient = minioClient;
    }

        }
    }

4.测试

@SpringBootTest
@RunWith(SpringRunner.class)
public class main {
  @Test
  public void test3(){
      try {
          // 如存储桶不存在，创建之。
          BucketExistsArgs bucketExistsArgs = BucketExistsArgs.builder().bucket("photo").build();
          boolean found = minioClient.bucketExists(bucketExistsArgs);
          if (found) {
              System.out.println("🪣已经存在 栓Q");
          } else {
              MakeBucketArgs makeBucketArgs= MakeBucketArgs.builder().bucket("photo").build();
              minioClient.makeBucket(makeBucketArgs);
              System.out.println("🪣创建成功");
          }
      } catch (MinioException e) {
          System.out.println("Error occurred: " + e);
      } catch (IOException | NoSuchAlgorithmException | InvalidKeyException e) {
          e.printStackTrace();
      }

  }
}

5.结果

🪣已经存在 栓Q
